Multiple IP's (from 2 different networks) on a single SQL 2005 Cluster

Hello there,

I'm currently building up a SQL 2005 Active/Standby cluster in a DMZ. I have three NIC's in each server.

Each NIC is connected to a different network:

192.168.100.1 is the public NIC

10.0.0.1 is the NIC used for communication betwen the cluster nodes (heartbeat)

192.168.200.1 is the admin NIC

I have installed my cluster using the 192.168.100.0 network for public access. This means that my SQL virtual ip is 192.168.100.10

Each server can be administered over the 192.168.200.0 network (admin) and the cluster/sql sever ip is available from the 192.168.100.0 (public) network.

Now for my question: How can I assign a ip address from my admin network (e.g.192.168.200.10)  to the existing SQL server cluster to make it available from my admin network while keeping the public ip.

Thanx in advance!
